This inventionfcontemplates; certaini new and'useful improveme'nts in ladders and the 10 object o the invention is an improved bracket designed to be secured to the up er end of a may be desired to prevent said u or end fron'ibearing rainspout or the "like outstanding from the wall .or roof of ahouse.

. A furtherobject of the invention is a simjusted ple, durable' and 'efi ici'ent construction of a device of the character described which may be a plied to ladders of difierent widths and I l Whic may be quickly and conveniently adto com ensat'e for the pitch ofa roof or the angle inclination of the ladder. With these and other objects in view, that will more fully appear as the description proceeds, the inventlon consists in certain constructions and arrangements of parts that I shallhereinafter fully describe and claim.- For a fullunderstanding of the invention and the merits thereof, reference is to be had to the following descri tion and the accompanying drawing, in w ich:

Corresponding and like parts are'referred to in the following description and indicated in all the-vi f the drawing by the same reference aracters.

My improved bracket comprises a frame 1 pivotally iured to the upper end of the ladder and constructed in two side bars 2 and two cross bars 3 and g; In order to establish a pivot connection between the frame 1 and the ladder, the cross-har 3 is formed at its ends with outwardly facin sockets 5 and two tr'uhnions 6 are receive in said sockets, said trunnions being carried by disks 7 secured to the respective inner faces of the sides of the ladder at the u er end thereof.

' In order 'to 'adap t my improved bracket ed. To accomplish thispurlpose the crossbar 3 isiconstru'cte'd in two te esco'ping members, a threaded inner member 12 and a holmember fits, a nut 14 being adjustably mounted on the innermemb'er and bearing against the end of the outer me'mberto limit the. inward movement of said inner member and thus obviously regulating the length of he cross-bar 4'is formed in, 15 and 16, a bolt l7 the cross-bar. two overlapping'sections being secured in one end of the section 15 are arranged to bear against the work in an operat ve position,

In the practical use of -my improved frame is adjusted so that'it projects from the upper end of the ladder at the Proper angle, and the ladder is that tilted against the work bearing thereagainst as clearly ,shown .in Fi 4. 1

IVhile but one form of the invention is embodied ,in the description and'illu'strated in the'drawing, it is to be understood that various changes may be'madein the size, shape and proportion of the arts within the scope of the invention as de ed in theappended c aims.

1.". The combin ation with a ladder, of trunnions the ends of said cross-bar and adapted to secured to the innerfaces of the sides, thereof, a frame embodying side-bars and with the heads of the frame I Having thus described the invention, what V bear against said trunnions as and for the I purpose set forth.

2. 'llhe combmation with a ladder of trun- Q rame embodying'side-bars and a cross-ball,

nions secured to the inner faces of the sides thereof, a frame embodying side-bars and a cross-bar, the cross bar bemg formed in its ends with sockets receiving the respective trunnions, set screws mounted in the ends of 'said'cros's-bar and adapted to bear against 'the trunnions, and means for laterally adjusting the cross-bar to permit the sockets to be disengaged from the trunnions.

-3. The combination with a ladder, of a frame embodying side bars and a cross bar, plates secured to the ladder sides and having a socket and trunnion connection with the frame, the cross bar being constructed in inner and outer telescoping members, and the inner member being threaded, a nut working upon the threaded inner member and'be'aring against the outer member, and means for holding the frame atdifferent inclinations relative to'the ladder.

4. The combination with a ladder, of a the cross-bar being constructed inextensibly connected sections, plates secured to the inner faces of the ladder sides and having a socket and trunnion connection with the ends of the cross-bar, and means for holding the frame at, different inclinations relative to the ladder.
